Application filed March 8, 1915. Serial No. 12,833.

T 0 all whom it may concern:

Be it knownthat we, Gnouon G. Ross, HARRY E. Ross, and LEO D. Ross, citizens of the United States of America, residing at Greensburg, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Train-Pipe Couplings, of which the following is a specification, referencebe ing had therein to ing.

This invention relates to automatic train pipecouplings of" an; impact type, and has for its object to provide an automatic train pipe coupling of suchtype, in a manner as hereinafter set forth, with an automatic train pipe coupling head and auxiliary at tachments operated by the coupling of railroadcars or vehicles.

A further object of the invention is to provide an automatic train pipe coupling of an impact type provided with means, in a manner as hereinafter set forth, operated by the movementlof railroad cars or vehicles, for imparting an oblique movement to an automatic train pipe coupling head.

A further object of the invention :is to provide anautomatic train pipe coupling of an impact type with means, in a manner as hereinafter set forth, operated by the movement ofrailroad carsor vehicles, for transmitting a reciprocating motion, to be imparted to an automatic train pling head.

the accompanying draw- Further objects of the'invention are to provide an automatic train pipe coupling which is comparatively simple in its construction and arrangement. strong, durable, efficient and convenient in its use. readily attached to a car and comparatively inexpensive to manufacture and maintain.

With the foregoing and other objects in view, the inventionconsists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which :come within the scope of the claims hereunto appended.

-In the drawings, wherein like reference characters denote throughout the several views :Figure 1 is an exterior view of the automatic train pipe couplings, Fig. 2 is a sectional detail of an pipe concorresponding I partsautomatic train pipe coupling, Fig. 8 is a perspectiveview of an automatic train pipe coupling head, Fig. 4 is a View of an automatic train pipe coupling head equipped with a conduit hose and standard train pipe coupling. Fig. 5 is a view of automatic train pipe coupling heads locked in conjunction. Fig. 6 is a horizontal sectional view of the automatic coupling head.

Referring to the drawings in detail, A denotes the automatic train pipe coupling head provided with the beveled tongue A and the flared guiding hood A the purpose of which will be presently referred'to. The inner surface of the beveled tongue A provides the coupling face A said face having seated therein the gasket V, a longitudinal air passage V extends throughout the length of the device.

The reference character 13 denotes a hollow ball terminating in a tubular neck and contained in thecasing B, said tubular neck being attached to the automatic coupling head A, fitted in the casing B and seated on the hollow ball 13 is the socket B said ily be seen said extending portion may be of any desired shape but in this instance it is of a circular form,extending into the female tubular member D is the maletubular member 0 having the extending portion F similar to the extending portion F on the female tubular member D, the male tubular.

member C is provided with a suitable packing ring P, surrounding the tubular membersD and C, between extending portions F and F is the spring E maintaining said tubular members D and C in anextended position until force is applied to the automatic coupling head A greater than the tension of said spring, extending through openings provided inthe projecting portions F and F of the tubular members D 1 and C are the tie bolts Y, said tie bolts being held stationary in one of the said protrain pipe couplinghead Ahalf way and} returning in an angular direotijonto a po nt I jecting portions and being free as "mavens the other one, this arrangement providing" a means to limit the extensiorr 'of sa-icl tw" bular members.

' A means is provided as shown on Fig:4:- of the drawings, of connecting a ear" equipped with'the present standard'bf train pipe couplings with the automatic train pipe coupling described in the specifications and shown on'the drawings of the presefntiin vention, this object is accomplished by equippingaan automatic train pipecoupling head, ofthecharactershown on the drawings with the lock screw WV'and 'a'standard' hose and coupling'X, the attachment idescribed above maybe usedwhen iti quired. Generally is resew guiding .ho'od overlapping the automatic A near the corner- 0f- -the fiared guiding hood A3, on the-faceside the flared guiding I hoo'd A ;eXtendi ng--;acros s the automatic ,cou- I plingfhead A andextending forward and flaring outwardly from the face A forming with the top and: bottom portionsvof said flared guiding hood the socket A said socket being ;adapted to receive the point of a beveled tongue A ot'a mating automatic train pipecouplinghead, the flare of saidguiding hood A being adapted for the purpose of guiding the beveled tongue A of a"matingautomatic train pipe cou pling-head, on opposite car or vehicle into the socket A A of thebeveled tongue A said gasket beingadapted-tomate with a similar gasket in a mating automatic train pipe coupling:

coupling heads, of the" character described will .be lockedin conjunction.

As may readily be seen by referencen'tof the drawings,- when several cars or vehicles in a railroad train are in a curvated posi tion the arrangement shown at B; B, B andB will assist the automatic train pipe coupling-heads A to assume an oblique posi tion in-regard to the longitudinal position of the car bodies.

When the several cars and'vehicles are coupledtogethr in a railroad train, the 7 arrangement' ,ofthe tubular members, spring and tiebolts as-sho wn at, and C, E'and; Y, respectively, will permlt-a reciprocat ingi-motion to' be imparted to an automatic describing said automatic train pipe coupling,?the same consistsot': an; auto? matic icoupling head A fhaving'; af J'I'ace A3- capable of mating-at an angle with face of. a duplicate automatic coupling head, 011 013 posite'car'or vehicle, afiared guiding hood- A extending forward, at anangle on 4 three sides, onthe top and'bottom sides said flared a gasket V seated in the face train "pipe" coupling "head "bf this "character,
